After working for EcoClean — an industrial cleaning supplies company — for nearly 17 years, model-employee Inès believes it's time for a raise. Despite daily jibes from her incompetent and misogynistic co-workers (including Patrick, EcoClean's ineffectual owner), she remains professional and dedicated to the company's brand. When Inès confronts Patrick about her salary, he not only disparages her request but makes a lecherous pass at her. New intern Mélody witnesses this and jumps in to help, but in the process both women accidentally find themselves with blood on their hands. Spiraling more out of control by the minute, Inès and Mélody must conjure up increasingly maniacal solutions to cover their tracks — and clean up their mess.
